Isla Verde beach is close to the airport, from my understanding. We haven't been there yet, but will be going at the end of the month, because we are staying at a hotel in that area for one night before our cruise. I have heard it is one of the better beachs in San Juan itself. You would have to take a taxi both ways from the pier and back. I have also heard that Luquillo Beach is a really pretty beach, but that would be quite a long, expensive ride, have never done it yet. Maybe someday. I think there are beachs near the hotels in the Condado area also, which is closer to the pier, but heard that Isla Verde was better. Hope this helps.
